SHANGHAI, May 17, 2022 /PRNewswire=KYODO JBN/ --

To realize full combustion and reduce emissions, the engine of

automobile/motorcycle usually requires a temperature pressure sensor on the

intake manifold (TMAP) to control the air-fuel ratio quickly and accurately,

which can build a balance between power performance, fuel economy and

emissions. The automotive absolute pressure sensor with response time in

sub-millisecond is one of the key components in combustion engine system to

realize closed loop control. There is also the same requirement in the

gas-driven models to reduce emission with the pressure sensor near the gas

injector.

Semiconductor Supplier NOVOSENSE Microelectronics recently launched its NSPASx

series --- an automotive-qualified integrated absolute pressure sensor which

integrates the automotive-qualified absolute pressure MEMS die(NSP163x) and

signal conditioning IC(ASIC). The device adopts ASIC to calibrate and

compensate the output of MEMS die, which can convert pressure signals from

10kPa to 400kPa into Vout with a customized output range from 0 to 5V. The

internal MEMS die is based on the piezoresistive effect of high-sensitivity

monocrystalline silicon and is designed with advanced silicon-silicon bonding

CSOI MEMS micromachining technology which has been certified by IAFTF16949. The

whole wafer has 100% passed AOI and CP test and also the AEC-Q103

qualification, total accuracy is less than +/-1%FS during its life cycle.

The NSPASx series and MEMS wafer(NSP163x) are mainly used in intake manifold

pressure detection of vehicle/motorcycle, purging line pressure detection of

vehicle, vacuum boosting system (VBS) pressure detection of HEV/EV, thermal

runaway pressure detection of battery pack, as well as the car seat airbag

pressure detection.

Key features:

High accuracy and low power consumption:

High linearity and good stability without secondary calibration

100% temperature compensation

Output accuracy better than +/-1%F.S. at 0 degrees Celsius ~ 85 degrees

Celsius, better than +/-1.5%F.S. at -40 degrees Celsius ~130 degrees Celsius

Operating current less than 3mA

Multiple output modes with good portability for various applications:

Ratio-metric analog output

Absolute analog output

Automobile-level standard with high reliability and stability:

Over-voltage and reverse-voltage protection between -24V to 28V

Directly supplied by high voltage up to 18V

AEC-Q100 qualified

Quick response to control the ratio of air-fuel speedily:

Better than 0.8ms response time

Customization for different applications with high flexibility:

Support the customization of pressure range from 10kPaA to 400kPaA

MEMS wafer(NSP163x) can also be customized

NOVOSENSE Microelectronics has self-developed MEMS/ASIC, packaging technology

and automatic calibration technology at multi-pressure and multi-temperature

points, which can support MEMS wafer and integrated device customization to

meet the requirements in multi-applications.
